Signs and tests:

Inspection of the abdomen may show distention, and listening to the abdomen with a stethoscope (auscultation) may show abnormal sounds indicating decreased gastric motility.

An eye examination may show sluggish pupil reaction. Examination by touch (palpation) or tapping (percussion) may indicate a distended bladder. Blood pressure examination may show a decrease upon standing (postural hypotension).

Occasionally, other symptoms may indicate disturbed functioning of the autonomic nervous system, including high blood pressure, rapid or slow heart rate, irregular heart rhythms, excessive sweating, difficulty swallowing, or other symptoms.

Special measurements of sweating and heart rate are called "autonomic testing" and can assist in diagnosis and treatment.

An upper GI (gastrointestinal) examination with small bowel series may show decreased motility, delayed emptying of the stomach, or other abnormalities and may be used to rule out physical obstruction as a cause of vomiting or other GI symptoms.
An EGD (esophagogastroduodenoscopy) is used to rule out physical obstruction as a cause of GI symptoms.
An isotope study may indicate gastroparesis (decreased gastric motility).
A VCUG (voiding cystourethrogram) or other tests of bladder function may show a flaccid bladder (inability of the bladder to contract and empty).

Other tests for autonomic neuropathy are guided by the suspected cause of the disorder, as suggested by the history, symptoms, and pattern of symptom development.
